In Puro-Puro, a net and empty jars are required to catch any implings.

In Gielinor, they can also be caught barehanded or while wielding any item, with or without an empty impling jar. Without an empty jar player will immediately receive the loot from the impling, instead of the impling itself.

Once these requirements have been met the player simply needs to click on the impling, and the character will attempt to catch it, though there is a chance of failure, in which case the character will continue trying to do so until it is caught. Bind, Snare or Entangle could be cast on implings to prevent them from moving for different periods of time.

Capturing a ninja impling will grant the player either 339 (if caught on Puro-Puro) or 481 (if caught on RuneScape) Hunter experience.

Because many players ignore baby or young impling when encountered, the spawn rate of rarer implings is hindered. The faster a lower level impling is caught, the faster the respective spawn point will generate a new, possibly rarer, impling. Players looking for rarer implings would do well to catch any low level implings they see in order to encourage the respawning of higher level implings.
